摘要
目的 评估初次膝关节表面置换术的早中期疗效,分析主要并发症发生的原因和预防方法 .方法 回顾分析自2000年1月~2007年12月,本组接受初次膝关节表面置换术的140例176膝,获得随访的患者129例160膝,平均随访时间为(35±8)个月(16~98个月).术前和随访时对患膝进行KSS 和HSS评分,关节活动度检查,所得数据采用SPSS 17.0统计学软件进行统计学分析.结果 术后膝关节感染4例(2.5%),其中2例为术后5~6年出现感染,与患者不恰当的局部注射治疗有关.膝关节关节僵硬(活动度小于75°)11例((6.8%),深静脉血栓形成1例(0.8%),假体无菌性松动1例(0.6%).随访时膝关节表面置换术后HSS及KSS评分均较术前显著提高,优良多达90%以上.膝关节活动度从术前的(87.7±27.7)°提高至术后的(108.8±21.9)°(t=2.272, P〈0.01).结论 初次膝关节表面置换术对于消除膝关节疼痛,改善关节的活动功能效果明显,术后早中期的并发症发生率低.
Objective To evaluate the outcomes and complications of primary total knee arthroplasty. Methods A retrospective review was given to the date from 129 cases (160 knees) undergoing primary total knee arthroplasty between January 2000 and December 2007. The average follow-up time was (35 ±8) months. Each patient was assessed according to KSS and HSS. The range of knee joint motion was also evaluated. Results The infection rate after operation was 2.5% (4 cases). The range of motion less than 75° occurred in 11 knees (6. 8% ). The deep vein thrombosis was occurred at one patient and loosening of tibia prosthesis also occurred at one patient. The average of HSS was significantly increased from (39. 9 ±8. 0) preoperatively to (84. 1 ±12. 1 ) at follow -up( t = 1. 087, P 〈 0. 01 ). The average of KSS was also significantly increased at follow-up. The knee motion range was significantly improved from ( 87.7 ±27.7 )° preoperatively to ( 108. 8 ± 21.9 ) ° during follow-up ( t = 2. 272, P 〈 0. 01 ). Conclusions The TKA is an effective method to improve the function of the knee with end-stage arthritis.
